Set Date and Time on PC, PXI, and PXI-RT using DAYTIME protocol

This example illustrates how query a server using the DAYTIME protocol and set the date and time of the LabVIEW Real-Time target. The example uses two NIST time servers, time-a.nist.gov and time-b.nist.gov. See the link below for more information on these time servers. You can get a list of other public time servers from the Internet.

After establishing a connection to the DAYTIME server, the VI retrieves the current time from the server and sets the time on the RT controller. FieldPoint targets are capable of automatically updating their date and time from a Windows PC running the Logos Time Server. The advantage of using a DAYTIME server is that you do not need a Windows PC running the Logos Time Server to get the current date and time. This example can be used on any LabVIEW Real-Time target.

DAYTIME is simpler version of the well known NTP (Network Time Protocol) standard.

This example uses DAYTIME protocol, not NTP
This example uses the DAYTIME protocol instead of NTP to retrieve the time from the NIST server.
